Detailed Description

Holds a fragment replay plan for the recovery of a RangeServer.

This plan consists of a set of fragments and associated range servers that are responsible for replaying the fragment as part of the recovery operation.

Definition at line 53 of file ReplayPlan.h.

Member Function Documentation

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::clear ( )

inline

Clears the plan.

Definition at line 109 of file ReplayPlan.h.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::decode_internal	(	uint8_t	version,
		const uint8_t **	bufp,
		size_t *	remainp
	)

overrideprivatevirtual

Reads serialized representation of object from a buffer.

Parameters

version	Encoding version
bufp	Address of destination buffer pointer (advanced by call)
remainp	Address of integer holding amount of serialized object remaining

See also: encode_internal() for encoding format

Implements Hypertable::Serializable.

Definition at line 133 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::encode_internal ( uint8_t ** bufp ) const

overrideprivatevirtual

Writes serialized representation of object to a buffer.

Parameters

bufp	Address of destination buffer pointer (advanced by call)

Encoding is as follows:

Encoding	Description
i32	Entry count
For each entry:
FragmentReplayPlan	Fragment replay information

Implements Hypertable::Serializable.

Definition at line 126 of file ReplayPlan.cc.

size_t Hypertable::Lib::RangeServerRecovery::ReplayPlan::encoded_length_internal ( ) const

overrideprivatevirtual

Returns internal serialized length.

Returns: Internal serialized length

See also: encode_internal() for encoding format

Implements Hypertable::Serializable.

Definition at line 99 of file ReplayPlan.cc.

uint8_t Hypertable::Lib::RangeServerRecovery::ReplayPlan::encoding_version ( ) const

overrideprivatevirtual

Returns encoding version.

Returns: Encoding version

Implements Hypertable::Serializable.

Definition at line 95 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::get_fragments ( vector< int32_t > & fragments ) const

Fills a vector with all of the fragment numbers that are part of this replay plan.

Parameters

fragments reference to vector to hold fragment numbers

Definition at line 58 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::get_fragments	(	const string &	location,
		vector< int32_t > &	fragments
	)		const

Fills a vector with fragment numbers assigned to a specific location in this replay plan.

Parameters

location	location (range server) for which to get fragment numbers
fragments	reference to vector to hold fragment numbers

Definition at line 64 of file ReplayPlan.cc.

bool Hypertable::Lib::RangeServerRecovery::ReplayPlan::get_location	(	int32_t	fragment,
		string &	location
	)		const

Given a fragment number, return location it is assigned to.

Parameters

fragment	fragment number to look up
location	reference to string to hold returned location

Returns: true if found, false otherwise

Definition at line 84 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::get_locations ( StringSet & locations ) const

Fills a set of location strings that represent all of the locations (range servers) that are part of this plan.

Parameters

locations reference to string set to be filled with locations

Definition at line 73 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::insert	(	int32_t	fragment,
		const string &	location
	)

Modifies the recovery replay plan by inserting a fragment and associated location (range server) responsible for replaying that fragment.

If the fragment already exists in the plan, then the associated location information is updated with the new location.

Parameters

fragment	fragment to replay
location	proxy name of range server responsble for replaying fragment

Definition at line 40 of file ReplayPlan.cc.

void Hypertable::Lib::RangeServerRecovery::ReplayPlan::remove_location ( const string & location )

Parameters

location proxy name of range server to remove
